protected:
 virtual void OnRowErrorTextNeeded(System::Windows::Forms::DataGridViewRowErrorTextNeededEventArgs ^ e);

protected virtual void OnRowErrorTextNeeded(System.Windows.Forms.DataGridViewRowErrorTextNeededEventArgs e);

abstract member OnRowErrorTextNeeded : System.Windows.Forms.DataGridViewRowErrorTextNeededEventArgs -> unit
override this.OnRowErrorTextNeeded : System.Windows.Forms.DataGridViewRowErrorTextNeededEventArgs -> unit

Protected Overridable Sub OnRowErrorTextNeeded (e As DataGridViewRowErrorTextNeededEventArgs)

Parameters

e: DataGridViewRowErrorTextNeededEventArgs

A DataGridViewRowErrorTextNeededEventArgs that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnRowErrorTextNeeded method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors

When overriding OnRowErrorTextNeeded(DataGridViewRowErrorTextNeededEventArgs) in a derived class, be sure to call the base class' OnRowErrorTextNeeded(DataGridViewRowErrorTextNeededEventArgs) method so that registered delegates receive the event.
